[CentOS] problem with a repo

Hello, I've got rpmforge and epel on centos 5.3. I'm trying to do an install of perl-Image-Info for spamassassin image scanning. The package was picked up in rpmforge since first, but it is failing to install because a dependency is missing. I added perl-Image-Info to rpmforge's excludepkgs line and tried to install the package again this time thinking it would pull from epel. This did not occur yum still tried to fetch from rpmforge. For my excludepkgs line i tried:

excludepkgs=package1,package2,perl-Image-Info

and since the changes weren't picked up i did:

excludepkgs=package1 package2 perl-Image-Info

Any help appreciated. Thanks. Dave.
